摘要

In order to control the position of electro-hydraulic servo motor system, a strategy of CMAC (Cerebella Model Articulation Controller) neural network and PID hybrid control is presented in this paper. Reference input signal is transmitted to the CMAC neural network, to take charge of accurate position control and enable the system to take feed forward compensation steps. Output signals from the CMAC network and a conventional PID controller are weighted and integrated to constitute an overall output signal, which then acts on the plant. Thus, good regulating performance is guaranteed in the initial control stage and also in case of characteristics deviations of the plant. Simulation results show that the control strategy can improve the control performance, and is effective and practicable.
